Abstract

An electric equipment includes: an electric component box; a control board accommodated in the electric component box and provided thereon with a heat-generating electric component; a heat sink thermally connected with the electric component; and a sheet material provided between the electric component box and the control board, wherein the sheet material is made of an elastic material and provided with an opening section through which the heat sink projects outward, the opening section is provided with a convex section formed integrally with the sheet material and configured to be elastically deformed to engage the sheet material with the heat sink, and the electric component box is provided with a heat sink hole through which the heat sink and the convex section project outward of the electric component box. An air conditioner is provided with such electric equipment.

First claim

The invention claimed is:

1. An air conditioner comprising:
a blower comprising a fan configured to suck air from a shaft direction on an inlet side and blow the air out in a circumferential direction on an outlet side;
a heat exchanger;
an electric component box comprising a heat sink attached at a position opposing the blower and a heat sink hole through which the heat sink projects outward of the electric component box, wherein the electric component box and the heat sink are arranged upstream of the heat exchanger and face the inlet side of the fan.

2. The air conditioner according to claim 1 , wherein the electric component box is formed with a cut-and-raised piece having a projection length larger than a projection length of the heat sink at a peripheral portion of the heat sink hole.

3. The air conditioner according to claim 1 , wherein the electric component box comprises, on a surface in which the heat sink hole is formed, a resin molded-component having a projection length larger than a projection length of the heat sink.

4. The air conditioner according to claim 1 , wherein the air conditioner is a built-in type air conditioner.

5. An electric equipment comprising:
an electric component box, the electric component box comprising a heat sink hole;
a control board accommodated in the electric component box and comprising a heat-generating electric component;
a heat sink thermally connected with the electric component; and
a sheet material made of an elastic material provided between the electric component box and the control board, the sheet material comprising an opening section through which the heat sink projects outward, the opening section comprising a convex section formed integrally with the sheet material and configured to be elastically deformed to engage the sheet material with the heat sink,
wherein the heat sink and the convex section project outward of the electric component box through the heat sink hole, and a gap between the heat sink and the electric component box is closed by the sheet material.

6. The electric equipment according to claim 5 , wherein an H-shaped slit is formed in a position of the opening section of the sheet material in a state before the sheet material is assembled into the electric equipment.

7. The electric equipment according to claim 5 , wherein the sheet material is formed of a flame-retardant material which has a large surface friction coefficient and is elastically deformable.

8. The electric equipment according to claim 7 , wherein the sheet material is an aramid paper.

9. An air conditioner comprising:
a main body comprising an inner space partitioned into a blower chamber and a heat exchange chamber by a partition plate;
a fan provided in the blower chamber;
a heat exchanger provided in the heat exchange chamber;
an electric component box provided in the blower chamber; and
an electric equipment comprising a control board disposed in the electric component box and comprising a heat-generating electric component, a heat sink thermally connected with the electric component, and a sheet material disposed between the electric component box and the control board and closing a gap between the heat sink and the electric component box.
